It's very interesting to even hear the words "trade", "guild" and so on, along with the heavy emphasis on politics; something that we tend to now associate with the much maligned PT. It's as if Lucas completely ditched all of that and just went straight for an action story through line for ANH, with the political baggage sidelined.

Also knowing WHEN the first draft was written, along with the fact that Tatooine is a desert planet makes you see the MAJOR influence "Dune" also had on the young Lucas. Both very political with great old families plotting and scheming along with guilds and associations.
